what makes my 1987 chevy sprint act like it has no gas on a full tank

when driving my 1987 chevy sprint will go fine for a bit then it will bog down with no power like it is out of gas. I pull over and wait then try again it will go again . I never know when it will do this and i am put in the middle of traffic and such.. can you help me find and fix the problem

Sounds like filter, or, number of things really. When you say "pull over and wait then try again..." do you turn your car off, or pull over and let it idle? If it is your fuel filter, you may want to be sure your tank is clean, it could be junk in the tank, clogging your pump. The pump itself is in the tank making it a pain in the tush to get to. Is it EFI, carb? Injector might be clogging.

thx for your response. I changed all filters, replaced the fuel pump
and to answer if I pull over and let it idle I wish I had that option.
The car simply dies no power at all . The car starts to choke and I
have seconds to find a place to pull over or I get stuck right there,
sometimes in the middle of angry traffic.

When is the last time it was tuned up? May be in cap & rotor, plugs & wires. Also check for vacuum leaks, TBI base gasket, intake manifold snugged up. Run fuel injection cleaner threw, maybe find a place to have the injectors cleaned.
